And “Hillary for Prison” shirts could be spotted across the city, as vendors lined the streets hocking a slew of controversial shirts to convention-goers.

Clinton, the presumptive Democratic presidential nominee, was cleared of wrongdoing by the Justice Department in the investigation of her use of a private email server while she was secretary of State. But in clearing Clinton of criminal charges, FBI Director James Comey slammed Clinton’s “extreme carelessness” in working with sensitive information.

The chants typify the concerns about party unity leading up to the convention. These concerns have only been exacerbated by the recent release of DNC emails that show party officials discussing ways to undermine Sanders's presidential primary challenge to Clinton.
